No matter how easy or hard something is, there will be someone who is unhappy. "Can't please everyone" isn't just a saying, it's reality.
There are people who find everything easy and beg for more challenging/engaging content, then when GM listens and adds things like that, there are people who complain it's too hard.
There are lots of people who successfully complete these challenges every day and enjoy them. If they were made easier it wouldn't be as fun.
A very large part of the challenge of this game is building kit to be able to kill tougher enemies, and practicing techniques to make that happen.
Calling to make something easier because you can't do it, while there are many people who can, seems short sighted to me.
As an alternative solution, would you consider accepting tailored advice on your kit and technique to help clear these quests? I'd be willing to wear kit equivalent to yours and attempt one to see how it compares to my normal experience
